Abstract

PURPOSE: To provide an applicator coil adapted for a selective treatment on a projecting part of the human body by providing a coil substantially having the shape of a spherical zone deformed into an ellipse. CONSTITUTION: An applicator coil almost has the shape of a spherical zone deformed like an egg or ellipse and includes a wire winding 10 deformed to match the shape and wound in a number of layers. Winding density is slightly greater at narrow ends than at wide ends, and the wire winding 10 is put in a plastic container 12. The applicator coil is provided with devices 24, 26, 28 supplying a treating fluid, and a plurality of electrodes 32 can be connected to an adaptable generator and are connected to a receiver coil, so that a low-frequency voltage corresponding to the receiver coil is induced via the wire winding 10; i.e., a cup shape deformed from a large opening into a small one is closely pressed against a projecting part of the body to make an effective treatment possible.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an applicator coil used in an electromagnetic treatment device.

0002

BACKGROUND OF THE INVENTION An applicator coil is known from the US Pat.

[0003] Applicator coils of this type are used in therapeutic treatments by alternating electrolysis. In normal medical and veterinary medicine, the frequency of this alternating electrolysis is preferably set to a low frequency of 20 hertz or less. This electrolysis must be shaped as closely as possible to a sinusoidal curve. Electrolysis is
It can be used to induce low frequency alternating current in an implanted receiver coil or directly for processing. This receiver coil forms part of a device for enhancing skeletal or tissue growth (U.S. Pat.
54 995 and 3 890 953).

Conventional hollow cylindrical applicator coils are primarily and primarily used for treatment of the extremities or trunk, and for this purpose:
The aforementioned is pressed across the part to be processed. However, conventional applicator coils are not well suited for selectively treating prominent body parts such as the shoulders or face.

The present invention therefore provides an electromagnetic treatment device for generating low frequency alternating electrolysis, which is particularly adapted to the selective treatment of protruding parts of the human body and which, if desired, can also be used on the animal body. The purpose is to provide applicator coils.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the invention will be described in detail with reference to the drawings.

The applicator coil shown in the drawings has approximately the shape of a spherical zone modified like an egg or an oval. The applicator coil is correspondingly modified and comprises a wire winding 10 wound in multiple layers. The loop of wire winding 10 is substantially oval or trapezoidal with rounded corners. The winding density is somewhat greater at the wide end than at the narrow end. The wire winding 10 is contained in a plastic container 12. The plastic container 12 consists of outer and inner shells 12a, 12b having flange-shaped edges 15, 16, respectively.
2b are glued or welded together. outer shell 1
At the narrow or sharp end of 2a, there is a handle 14.
is attached. The applicator coil has a small opening 18 which is connected to the outer shell 12.
It is defined by the curved part of a. Wide end 2
0, the applicator coil is substantially flat and raised from the flange 15 onwards. The wire winding 10 has a plurality of terminals 21 mounted within the handle 14 and connected to a connecting cable 22. By means of this connecting cable 22, the applicator coil is connected to a generator unit which generates a low frequency sinusoidal alternating current. The frequency is
Preferably it is variable between about 2 and 20 Hertz.

According to a preferred construction, the applicator coil is provided with a device for supplying treatment fluid. For this purpose, the applicator coil has an inner shell 1
It has a plurality of openings, that is, a plurality of nozzles 24, formed to penetrate through 2b. These nozzles 24 are connected to a supply line 28 via a branch line 26. A hose 30 is further connected to this supply line 28. This hose 30 is connected to a liquid or gaseous treatment medium during use of the applicator coil. This hose 30 then allows the electrolytic treatment to be assisted by applying a compatible fluid, such as a therapeutic medium or apparent force, to the surface of the body part being treated.

The plurality of electrodes 32 are connected to the plastic container 12.

It is applied galvanically or capacitively to the part of the body to be treated. Electrodes 32 can be connected to a compatible generator via leads, not shown. This generator generates an alternating voltage that is symmetrical or asymmetrical about zero, or a direct voltage with low frequency variations, such as a direct voltage to which an alternating voltage is applied. Alternatively, the electrode 32 may be connected to a receiver coil as shown in FIG. A corresponding low frequency voltage is induced in this receiver coil via the wire winding 10. Said receiver coil can be rotatably mounted within the plastic container 12 so as to be able to adjust the intensity and/or phase angle of the induced alternating voltage, and if necessary an asymmetrical alternating voltage with respect to zero or electrodes. It can be connected to a rectifier circuit to generate a fluctuating DC voltage for use.
